What Is The Difference Between Seminoma And Nonseminoma Cancer Of The Testicles
Different tumors: Over 90% of testis tumors are germ cell tumors which are seminoma, non-seminoma or mixed depending on the type of malignant cell. Classic seminoma is the most common testis tumor in adults. Almost all testis tumors are initially treated by surgical removal (orchiectomy). Then, based on the type of tumor and stage (aggressive characteristics, spread to lymph nodes) determines next treatment. ...Read moreSee 1 more doctor answer
Cancer is a group of diseases that is characterized by uncontrolled cell growth leading to invasion of surrounding tissues that spread to other parts of the body. Cancer can begin anywhere in the body and is usually related to one or more genetic mutations that allow normal cells to become malignant by interfering with internal cellular control mechanisms, such as programmed cell death or by preventing ...Read more
A lot: Stage refers to extent of cancer: generally stage 1 & 2 are early cancers; stage 3 involves spread to the nodes or structures in the middle of the chest; stage 4 involves spread to both lungs or other organs. Grade refers to the degree of abnormal appearance of the cancer when seen under the microscope- usually grades range from 1-3. ...Read moreSee 2 more doctor answers
Different Exam: An inguinal hernia is a hole in the groin muscles thru which a sac may protrude through, occasionally extending into the scrotal sac, next to the testicle. A testicular cancer presents as a growth within the testicle. These two abnormalities can be easily differentiated from one another by a careful physician examination. ...Read moreSee 1 more doctor answer
In testicular cancer, how often is there not a palpable mass ON the testicle and the cancer is INSIDE the testicle.Difference between ON and IN common?
Not meaningful diff.: This may be a semantic distinction more than a biological one. The cancer arises within the testicle, but may extend to the surface of that organ and bulge away from its surface. Thus, the tumor may FEEL to be on the testicle even though it has arisen from within it. Not all testicular cancer extends to the surface of the testicle. Palpation is clearly inferior to ultrasound examination here. ...Read more
Definitions: A tumor is a general term for a lump or mass in any location in the body. It can be cancerous or noncancerous. Breast cancer refers to malignant cells found in the breast. There are many benign/noncancerous tumors that can be found in the breast. Usually a needle biopsy is performed to determin if cancer is present. ...Read moreSee 1 more doctor answer
Different cancers: Sarcomas are very rare cancers that arise from bone, muscle, nerves, blood vessels or other connective tissues. Carcinomas are very common cancers that tend form glands. Most common examples are breast cancer, lung cancer, colon cancer, prostate cancer and renal (kidney) cancer, among others. ...Read moreSee 1 more doctor answer
Cancer v. Node: Lymph node is a structure in the body that screens lymph that is being drained from surrounding tissue against infection. Breast cancer is a collection of cells from breast ducts/lobules (usually) that have become immortal and often rapidly proliferative whereby they invade surrounding tissues depriving normal cells the ability to co-exist. Cancer cells may find their way to nearby lymph nodes. ...Read moreSee 2 more doctor answers
Great difference: The precancerous conditions which are believed to lead to cancer cannot spread beyond the superficial layer of the cervix. None of these precancerous conditions leads to cancer 100% of the time, but the worse they are, and the older the patient is, the more likely it is that cancer will develop. The point of pap smears is to detect the precancerous conditions so they can be removed. ...Read moreSee 1 more doctor answer
Completely different: Ovarian cancer is cancer of the ovaries, which is usually sporadic or "non-family history" cancer, but can be in about 10-20% of cases. Cervical cancer is cancer of the uterine cervix which is the lower end of the uterus. This is at least partly caused by the Human Papilloma Virus. Pap and HPV testing is very good for cervical cancer screening, while there is no good ovarian cancer screening yet ...Read more
What is the difference between metastasized brain cancer and cancer that started inside the brain?
Type of cancer cell: Cancer that metastasizes to the brain, originally started in a different part of the body. Common sites where these metastatic cancer cells originate include the lung, breast, kidney, skin (melanoma), and the colon. A primary brain cancer is one in which the cancer cell arises from within the brain. This is less common than metastatic cancer. ...Read more
Uneven look: Typically this word is used by radiologists to describe the look of testicles on ultrasound. It is not the same as a "mass" or "tumor" but simply suggests a hard to define "unevenness" in the look of the testicle on ultrasound. ...Read more
Overall course.: There are many differences between benign and malignant tumors. A benign tumor is often well differentiated, looks almost normal, and does not spread. A malignant lesion is usually poorly differentiated, ominous looking, and spreads to other sites by blood, lymphatics, and directly. It has a very bad course, and results many times in death unless aggressive treatment is done. ...Read more
Grade is key.: Brain tumors are rated by the world health organization grade, with higher grades generally being more aggressive. Stage is a terminology used in cancers outside of the brain, which describe how much a cancer has spread all over the body. Because brain tumors/cancers generally do not spread all over the body, we rarely use "staging" with primary brain tumors. ...Read moreSee 1 more doctor answer
What are the odds of having adenocarcinoma of the left lung and adenosquamous carcinoma of the right. Each is considered a primary cancer?
Not Common: The incidence of having 2 different primary lung cancers diagnosed at the same time is quoted between 2-16% (synchronous multiple primary lung cancers). If they are microscopically different tumors, they likely represent two different primary lung cancers rather than metastatic spread of one or the other. One or both could also be metastatic cancer coming from a different site in the body. ...Read moreSee 1 more doctor answer
The testicles are the two oval male gonads, or reproductive glands, located in the scrotum. The seminiferous tubules of the testis are the site of spermatogenesis and its leydig cells secrete testosterone. The term testicles is synonymous with testes or gonads. The singular form is ...Read more
